WSPR - 30m BAND - 25/10/2017
WSPR 13m (10.10 - 10.15 MHz) band activity data recorded for 3 x  24 hour period from 22/03/2017 to 25/03/2017
Data from the WSPR web site relating to monitoring and transmission from VK6YSF Northam Western Australia.

WSPR Frequency: Dial 10.1387 MHz USB (occupied bandwidth 10.1401 - 10.1403 MHz)

Grid location: OF88II

Local Time = +8:00 hours (0:00 = 8:00AM)

Transmission Power 37 dBm (5Watts)

SSN (Sun Spot Number): 23

Equipment: TS-930 at 5W, Radio computer interface

Antenna:  Doublet Antenna: Multi-band dipole with T-Match tuner and 4-1 Current Balun 

                Sloper Antenna:  Sloper Antenna  -  40 & 15m Bands with T-Match tuner  

                L Antenna:          L Antenna with T-Match tuner  

 

This exercise was to compare the L antenna and 40m Sloper with the main station antenna used for operations on the 30m amateur band.

 

Conclusion is that there is no compelling performance deference between the Antennas however the 40 Sloper showed a modest advantage for paths into North America.
